The present disclosure provides a curved display panel, including a first substrate and an opposing second substrate, the first substrate including a light-filtering layer. The light-filtering layer includes a first light-filtering unit, a second light-filtering unit, and a third light-filtering unit in a pixel unit; and at least one of an effective light-filtering area of the second light-filtering unit and an effective light-filtering area of the third light-filtering unit is larger than or smaller than an effective light-filtering area of the first light-filtering unit. A ratio of the effective light-filtering area of the second light-filtering unit to the effective light-filtering area of the first light-filtering unit is greater than or equal to about 0.9 and less than about 1, or is greater than about 1 and less than or equal to about 1.1.
